基于電力載波的智能路燈控制系統(tǒng)的設(shè)計(jì)與實(shí)現(xiàn)
[Abstract]:According to the current research situation of street lamp at home and abroad, the development trend and the national development plan of "ten thousand cities", aiming at the deficiency of regulating and controlling ability in the traditional street lamp system, the mode of switch lamp is backward, and the real-time state monitoring of lamps is not available. An intelligent streetlight control system based on power carrier is proposed. In order to achieve the purpose of energy saving and convenient management of street lamp, the following methods are adopted in the system design: (1) the data of street lamp is transmitted to cloud server in real time by using GPRS wireless communication technology, and the user can view the status of street lamp in time. In network communication, the adaptive algorithm of heartbeat interval is used to ensure the long TCP connection between client and cloud server; (2) single / double lamp controller can be controlled and data collected by power carrier communication technology; (3) PWM technology is used to realize the control and data acquisition of single / double lamp controller. LED luminance adjustment, Adjust the luminance of the street lamp according to the policy or user order, so as to achieve the "second energy saving" effect. The system consists of cloud server, concentrator, single / double lamp controller and client. Through the system users can conveniently remote control, state monitoring, brightness adjustment and data acquisition, improve the control mode of street lamps, and improve the energy-saving efficiency of street lamps. This paper first introduces the streetlight control system in terms of the significance of the research and the current research situation at home and abroad, and analyzes and sums up the requirements of the system. Then the design scheme of the system is given, and the key technologies such as GPRS, power carrier PWM dimming are discussed, and the feasibility of the scheme is analyzed. The software of each part of the system is designed, the principle frame of some hardware is introduced, and the GDW1376.2 protocol (DL- T645) used in the system is analyzed. Finally, the system strategy, remote control, data acquisition and other functions are tested. The system has stable function, good experience and meets the design requirements.
